STUDY OF WATER FLOW CALIBRATION FACILITIES WITH MULTI-FUNCTION AND HIGH ACCURACY

摘要

The paper describes a water flow calibration facility combined weighing method and master meter method. The flowmeter calibration system aims at obtaining a very high level of accuracy and assurance of product reliability. Moreover, a new method, synchronous pulse counting method, to improve the calibration accuracy and efficiency of master meter method is proposed. Experimental results show that the computer control system is reliable and the accuracy using weight method and master meter method is up to 0.066% and 0.076%, respectively.
